Choose your distance. Each category has limited registration spots.

Each runner will be gifted a custom swag bag, race materials, and run aid. Every participant is required to fill out a post registration waiver and intake form.

The CommonDad 100 is an unsanctioned 100-mile endurance challenge built for fathers who want to test themselves physically, mentally, and emotionally — and do it alongside a community that understands the weight we carry every day.

This is not a race for medals or podiums.
It’s a proving ground.

Come prepared with your own pacers and support team for aid stations. Fuel at aid stations provided for runners if needed.
